' SPECIFICATION forming part of Letters Patent N 0. 652,780, dated July 3, 1900.

Application filed March 24,1899. Serial No. 710,360. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH J AUCH, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Lamp-Burners; and I do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a view, partlyin elevation and partly in vertical section, of a lamp containing my improvement.

My invention relates to an improvement in that class of lamp-burners which employ mantles which are raised to incandescence by the flame, the object being to produce a simple, compact, and convenient burner constructed with particular reference to providing for the protection of the mantles and keeping them in shape without the use of additional parts for the purpose.

With this end in view my invention consists in a lamp-burner having certain details of construction and combinations of parts, as will be hereinafter described, and particularly recited in the claims.

In carrying out my invention as herein shown I employ a mantle A, which may be of any suitable mesh and construction, its contracted upperend being furnished with a suspension-loop B, by means of which it is suspended from a hook 0, formed at the upper end of a wire mantle-support C, the lower end of which is bent to form a ring D, over which is spun the outwardly-rolled edge of a combined sheet-metal burner-cone and mantle-spreader E, made just large enough in diameter to fit closely within the open lower end of the mantle, whichit keeps not only from lateral or sidewise displacement, but

. also from shrinkingor collapsing under the effect of centrally-exerted suction or airpressure or from other causes present in lamp-burners employing mantles. The said combined burner-cone and mantle-spreader is itself held in place-by being set down over a collar F, located within and concentric with with inwardly-extending arms g, upon which the lower edge of the chimney H is supported, as clearly shown in the drawing. The upper edge of the said part E extends upward into the horizontal plane of the im inner tube J. The upper edges of both of these tubes, however, fall considerably below the upper edge of the combined burnercone and mantle-spreader E, which may be said to inclose a mixing-chamber L, to which airvis supplied from the air-chamber M,

formed by the body of the burner, which comprises a removable imperforate shell N and a perforated skirt 0, having long radi ally-arranged openings 0, a finely-perforated straining-cone P being located within the skirt O for straining the air entering the same through the long openings 0. The said shell N, upon which the gallery G rests, is formed at its upper end with a collar N, over which the gallery passes and which assists in preventing the collar from lateral displacement, the said collar N being concentric with the collar F, over which the lower end of the combined burner-cone and mantle-spreader E rests. The gallery G is secured to the shell N, with respect to which it is Vertically movable by means of two corresponding vertically-arranged arms Q Q, secured to the gallery and extending downward into the said shell, the lower edge of which is formed with looking projections R R, adapting the shell to be removably secured within the upper edge of the skirt 0, which isfurnishedwith a bead O for the purpose of this connection;

but these details of construction are not cs sential to a lamp-burner containing my in-' ven'tion, though I prefer to employa burnerbody of suificient' size and height to secure the chimney-gallery G, which is furnished 50 The said part I is 60 ample isolation between the flame and the oil within the fount S, which is thus prevented from becoming too much heated.

It will be understood, of course, that the main combustion of the commingled gas and air takes place within the mantle at a point between the top of the spreader and the upper edge of the combined burner-cone and mantle-spreader, although the initial combustion of the oil takes place at the wick. The gas generated by the initial combustion of the oil is commingled with the rising currents of air and burned at or above the top of the flame-spreader and above the upper edge of the combined burner-cone and mantie-spreader.

I by preference employ a tall chimney of a character designed to produce a strong draft, so as to draw the, flame upward and produce a strong combustion.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a combined burner-cone and mantle-spreader made in one and the same piece, and furnished with a mantle-support by means of which a mantle is supported at its upper end, the lower end of the mantle being entered by the said combined part which not only forms the burner-cone of the burner, but also prevents the mantle from lateral displacement and from collapsing.

2. In a lamp-burner, the combination with a burner-body formed with a concentric collar, of an inner and an outer wick-tube, an air-distributer or flame-spreader located within the upper end of the inner tube, a chimney-gallery formed with a collar which coacts with that of the burner-body in holding the gallery in place, and a combined burner-cone and mantle-spreader formed in one piece and provided with a mantle-support, and adapted at its lower end to set over the said collar of the gallery, whereby it is centered and held in place, the upper end of the said combined burner-cone and mantle-spreader extending above the upper ends of the inner and'outer wick-tubes and into the plane of the upper end of the air-distributer or flame-spreader, from which it is separated by an annular space.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
